Combinatorial BLAS(version 1.6.1, Jan 2018)

• MPI (see first a few lines in CMakeLists.txt)

• cmake >= 3.0

• C++11/C++14

1. normal compilation

   mkdir -p build cd ../build && cmake .. && make -j 

2. use COMBBLAS_DEBUG mode to enable combblas debug information output:

   mkdir -p build cd ../build && cmake -D COMBBLAS_DEBUG=ON .. && make -j 

3. use MAGIQ_DEBUG mode to enable magiq debug information output:

   mkdir -p build cd ../build && cmake -D MAGIQ_DEBUG=ON .. && make -j 

4. build on Shaheen

   first load proper modules:

   module swap PrgEnv-cray/6.0.4 PrgEnv-gnu module load cray-mpich 

   change the first two line of CMakeLists.txt, make following changes :

   -SET(CMAKE_CXX_COMPILER mpic++) -SET(CMAKE_C_COMPILER mpicc) +SET(CMAKE_CXX_COMPILER CC) +SET(CMAKE_C_COMPILER cc) 

   then do as above three sections suggested, by setting compiler to CC/cc you can only run the executable file with srun.

1. run(in $MAGiQ_ROOT/build) hard coded program:

   mpirun -np 16 ./magiq_src/magiqScal ../data/paracoder_lubm1B.nt 

2. run(in $MAGiQ_ROOT/build) sparql parser program:

   mpirun -np 16 ./magiq_src/magiqParse ../data/paracoder_lubm1B.nt ../examples/queries/lubm/q7.txt 1 

3. run on Shaheen

   example job script on Shaheen:

   #!/bin/bash #SBATCH --account=k1210 #SBATCH --job-name=test #SBATCH --output=otest #SBATCH --error=etest #SBATCH --nodes=1 #SBATCH --time=10:00 #SBATCH --hint=nomultithread #SBATCH --ntasks-per-node=1 #SBATCH --ntasks=1 #SBATCH --exclusive module swap PrgEnv-cray/6.0.4 PrgEnv-gnu module load cray-mpich cd /project/k1285/CombBLAS/ srun ./build/magiq_src/magiqParse ./examples/data/poster.nt ./examples/queries/poster/query.txt
